7 Claims.

The present invention relates to twisting tools particularly for automobile axles, but it is understood, of course, that a tool in accordance with the present invention may be used for any purpose and in any manner for which it may be found adapted or desirable.

The primary object of the present invention is to provide, in a manner as hereinafter set forth, a twisting tool embodying a novel construction, combination and arrangement of parts through the medium of which they may be operatively engaged with the axle or other work for twisting said axle or work accurately and to the desired extent.

Another important object of the invention is to provide a twisting tool of the character described which is reversible or invertible and which is adapted for use with various types of axles.

Other objects of the invention are to provide a twisting tool which will be simple in construction, strong, durable, highly efiicient and reliable in operation and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure l is a view in front elevation of a twisting tool in accordance with the present invention operatively mounted on an automobile axle, the upper portion of the jack being broken away.

Figure 2 is a view in side elevation of the twisting tool mounted on an axle, said axle being shown in cross section.

Figure 3 is a detail view in side elevation showing the supporting lever engaged with an axle of substantially I-shaped cross section.

Figure 4 is a view in front elevation of the elements shown in Figure 3.

Figure 5 is a top plan view of the twisting lever.

Figure 6 is a detail view in side elevation showing the twisting lever engaged with a round axle.

Figure 7 is a view in side elevation showing the supporting lever engaged with a tubular type of axle.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a supporting lever 1 having formed integrally therewith the opposed inner and outer jaws 2 and 3 respectively for disposition on opposite sides of the axle 4. The outer jaw 3 is provided with a shiftable work engaging face 5 which is adjustable through the medium'of a winged clamping screw 6 which is threaded through said outer jaw 3. If an axle of the I-type is being twisted, the jaw 2 and adjustable face 5 are shaped to accommodate the same, as illustrated in Figure 3 of the drawings and if the axle is of circular cross section, the jaw 2 and the adjustable face '5 of the jaw 3 are shaped for engagement therewith. If desired, the inner jaw 2 may be formed to accommodate removable, interchangeable faces for engagement either with an I type or tubular axle.

Horizontal wings 7 project laterally from the lever 1 for engagement beneath the axle 4 for supporting said lever against torsional strain or movement when the device is in use. A shim 8, or a plurality of shims, may be inserted between the axle and the wing 7 which is engaged with said axle.

Formed on the free end of the supporting lever 1 is an eye 9 for the reception of the transversely disposed, removable pin 10. The pin 10 projects laterally beyond the eye 9 and the purpose of this pin will be presently set forth.

The reference numeral 11 designatesv a twist- .85 ing lever which is engageable with the axle'at a point adjacent to the lever 1, said twisting lever 11 being provided with the oppositely inclined jaws 12 and 13 between which the axle is received. The lower portions of the jaws 12 "-110 and 13 are provided with transverse grooves 14 for the reception of the lower portion of the axle when said axle is of the I type. This is illustrated to advantage in Figure 2 of the drawings. The jaws 12 and 13 are adapted to have removably mounted therein the faces 15 of a shape conforming to the type of axle being twisted. On the free end of the twisting lever 11 is a substantially flat, circular head 16.

The reference numeral 18 designates a jack, l-'00 preferably of the pneumatic or hydraulic type which is mounted on the pin 10. To this end the jack 18 is provided with a bifurcated base portion 19 which straddles the pin 10. The head 7 20 of the jack 18 is engaged beneath the head 16 -l05 of the twisting lever 11. Consideration of Figure 1 of the drawings will reveal that the pin 10 is of a length to permit the jack 18 to be disposed beneath the head 16 of the lever 11.

In use, levers 1 and 11 are engaged with either end portion, of the axle or at any point along axle substantially as shown in Figures 1 and 2 of the drawings. Then, when the jack functions, pressure is exerted in opposite directions on the levers with the result that the lever 11 twists the axle as desired. The levers may, if desirable or necessary, be inverted and operatively engaged with the axle.

It is believed that the many advantages of a twisting tool constructed in accordance with the present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is tobe understood that changes in the details of the construction and in the combination and arrangement of parts may be resortedto which will fall within the scope of the invention as claimed.

Having thus described my invention, what I claim as new is: v

1. An axle twisting tool comprising a.1ever, means on one end of the lever foroperatively engaging said lever with the axle, a "twisting lever operatively engageable with the axle, a jack mounted on the first named lever and operatively engaged with the second named lever for actuating said second named lever, and a member extending from the first-named lever and engageable with the axle for supporting said first-named lever against torsional strain.

2. An axle twisting tool comprising a lever operatively engageable with the axle, means on the lever engageable with the axle for supportmg said lever against torsional strain, a twisting lever operatively engaged with the axle, and means engageable with the levers for actuating the second named lever.

3. An axle twisting tool comprising a lever, means on the lever for mounting said lever on the axle, wings projecting laterally from the lever for engagement with the axle for supporting said lever against torsional strains, a twist ing lever, means for operatively mounting the twisting lever on the axle, and a jack engaged with the free end portions of the levers for actuating the twisting lever.

4. An axle twisting tool comprising a lever, means on one end of the lever for connection with the axle, an eye on the other end of the lever, a transverse pin removably mounted in the eye, a twisting lever, means on one end of the twisting lever for engagement with the axle, a

jack mounted on the pin and engaged with the other end of the twisting lever for actuating said twisting lever, and means on the firstnamed lever engageable with the axle for supporting said first-named lever against torsional strain.

5. An axle twisting tool comprising a support ing lever, opposed jaws on one end of the sup-- porting lever engageable with the axle for mounting the lever thereon, wings projecting laterally from the sides of the supporting lever and engageable with the axle for suporting the lever against torsional strain, a transverse eye on the free end of the supporting lever, a removable pin mounted in the eye and projecting therefrom, a twisting lever, opposed on one end of the twisting lever engageable with the axle, a head on the free end of the twisting lever, and a jack mounted on the pin and operatively engaged with the head for actuating the twisting lever.
